Please click on the calibre number of your Seiko watch.


The "Calibre number" is on the rear case (Circled in Green).

You ONLY require the first two characters (Circled in blue).

Not the six digit serial number (Circled in Red).


There are no "Calibre Numbers" beginning with an "S", it will be a number 5.

The "Model Reference" does begin with an "S", but it is NOT on the watch. See bottom of this page.
